“…It is with great achievement to note that this research paper considers the WBC with conventional parameters coupled to the RCSJJ model which remain not yet been investigated and the interest in coupling both systems with separate rich behaviors is to obtain complex characteristics like chaos which find wide application in security regarding encryption of sEMG signals [46,47], communication [48] and network [49,50]. This paper then further realized the interesting application of security with the success reported in encrypting a biomedical image.…”

This paper recounts the dynamical investigations and microcontroller validation of Josephson junction (JJ) driven by Wien bridge circuit (WBC). Relying on the stability analysis of two equilibrium points found in JJ driven by WBC (JJDWBC), it is revealed that one equilibrium point is unconditionally stable while the other equilibrium point is unstable. The JJDWBC exhibits reverse period-doubling bifurcation, periodic attractors, period-doubling bifurcation, bistable chaotic attractors, and different presentations of monostable chaotic attractors. Partial and total amplitude controls are achieved by adding two controller parameters into the rate equations of JJDWBC. Finally, the microcontroller implementation is used to validate the dynamical behaviors found in JJDWBC.

<p>How are we able to fix it so as to theoretically go over it, if the optimality and efficiency of the orbital angular momentum (OAM) multiplexing technique in a multi-input multi-output (MIMO) system fails in practice $-$ something that technically causes a considerable reduction in the maximum achievable value of the transceiver's degree-of-freedom? Is the aforementioned challenging issue theoretically interpretable?</p>

The sixth generation (6G) wireless communication has significant impact due to massive connectivity and higher data rate. 6G is enhanced with Free Space Optical (FSO) communication in which the optical data is transmitted with a free spectrum license and higher security. But atmospheric circumstances have an impact on how well FSO communication works. The novel detection approach is proposed in this paper to enhance performance by mitigating the effect of atmospheric turbulence. Initially, the input signal is modulated with an On-Off keying (OOK) based modulation technique and transmitted through FSO communication channel. On the receiver side, signal detection can be accomplished with hybrid optimization Particle Swarm Hill Climbing Algorithm based (PSHCA)-U-net. The U-net architecture is modified to enhance the U-net performance by optimizing the hyperparameters with a hybrid PSHCA algorithm. Tests are conducted using various atmospheric weather scenarios on the proposed PSHCA-U-net model.Finally, simulations are performed to determine the performance of a proposed architecture and evaluated using Bit Error rate (BER), accuracy, transmission time, latency, spectral efficiency etc. Using the proposed approach, the spectral efficiency and latency are improved with 100 Gbps/Hz and 1ms. In terms of BER and other performance measures, the proposed solution outperforms the current strategy. It shows the superiority of a proposed approach while considering 6G parameters.
